Eusebio Di Francesco's men played out a thrilling 3-3 draw at Stamford Bridge in Group C two weeks ago but ran away with the return clash to replace the Premier League champions at the top of the standings on Tuesday.

El Shaarawy headed into the match on the back of a spectacular winning goal against Bologna last Saturday and he produced another one for the highlights reel – lashing past Thibaut Courtois first time from 25 yards after 39 seconds.
